Crowbar

Abstract

A crowbar includes a lower portion, a middle portion, and an upper portion. The lower portion has a tip portion with a bearing surface. The middle portion is an offset portion. The upper portion has a plum line surface, which is disposed at an angle of about 90 degrees to the tip portion/bearing surface. The crowbar is useful in removing material from poorly accessible regions such as ceilings or floor - wall corners. For example, the crowbar can readily remove baseboards of partition walls, and wood lath from ceiling beams and is useful in lifting heavy objects and the like.

The embodiments of an invention in which an exclusive property or right is claimed are defined as follows: 
     
       1. A crowbar comprising: an upper portion containing a longitudinal reference axis;   a middle offset portion connected to said upper portion and having a shifted end distal to said upper portion, said shifted end being displaced from said longitudinal reference axis in an outwardly transverse direction by a predetermined distance; and   a lower portion connected to said shifted end and including: (a) a pointed end distal to said middle offset portion;   (b) a bearing surface coterminous with said pointed end and transverse and distal to said upper portion;   (c) an extension connected to said shifted end and substantially parallel to and spaced from said longitudinal reference axis for providing clearance behind and above said pointed end; and   (d) a concave interval between said extension and said bearing surface having a C-shaped centerline, said concave interval having a crest displaced from said longitudinal reference axis in said outwardly transverse direction, said bearing surface being disposed at an angle of about 90 degrees to said longitudinal reference axis.     
     
     
       2. The crowbar of claim 1 wherein said middle offset portion has a surface which is offset a specified distance from the longitudinal reference axis. 
     
     
       3. The crowbar of claim 1, wherein said lower portion having said pointed end portion has a tapered thickness and a tip portion and a slot; and wherein said lower portion has a reverse bend portion and has a straight portion; and wherein said pointed end portion and the reverse bend portion and the straight portion together have a "question mark" shape. 
     
     
       4. The crowbar of claim 1, wherein said upper portion includes a straight portion, and pointed end portion which has a surface that is disposed at an angle of about 45 degrees from the longitudinal reference axis. 
     
     
       5. The crowbar of claim 4, wherein said upper portion having a straight portion has a lower thickness and has an upper thickness. 
     
     
       6. The crowbar of claim 5, wherein said lower thickness is larger than the upper thickness. 
     
     
       7. The crowbar of claim 3, wherein the tip portion and the slot are symmetrically about the bearing surface axis. 
     
     
       8. The crowbar of claim 3, wherein the tip portion is a flared tip portion. 
     
     
       9. The crowbar of claim 5, wherein said upper portion having a straight portion has a transverse thickness which is about equal to the lower thickness. 
     
     
       10. The crowbar of claim 4, wherein the upper portion having a pointed end portion has a tapered thickness and has a flared tip portion.
